[0002] The treadmill is a common fitness equipment in homes and gyms. It is the simplest type of home fitness equipment today and the best choice for home fitness equipment.

[0003] The treadmill in the prior art includes an armrest assembly and a main body assembly. In order to reduce the space occupied by the treadmill, the main body assembly is rotatably connected to the armrest assembly. When the treadmill is not in use, the main body assembly can be rotated counterclockwise to make the main body assembly in a roughly vertical state to reduce the space occupied by the treadmill. When the treadmill needs to be used, the main body assembly is rotated clockwise to place the main body assembly horizontally.

[0004] However, there is no buffer mechanism between the treadmill main assembly and the handrail assembly in the prior art, and when the main assembly rotates clockwise, it is easy to fall suddenly, which may cause damage to the main assembly. Utility Model Content

[0020] Based on the above technical solution: the first connector is connected to the crossbeam through the rotation of the vehicle body, and the first connector can rotate relative to the crossbeam, so that after the main body assembly is unfolded, the end of the damper can pass over the crossbeam, thereby preventing the damper from applying supporting force to the unfolded main body assembly.

[0021] A further improved solution: a second connector is provided on the armrest assembly, and the damper is rotatably connected to the armrest assembly via the second connector.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by users of the technology in this field without creative work belong to the protection scope of the utility model.

[0040] refer to Figures 1 to 4 , a foldable treadmill, comprising a handrail assembly 1 and a main body assembly 2 rotatably connected relative to the handrail assembly 1;

[0041] A damper 3 is provided between the main body component 2 and the armrest component 1 to prevent the main body component 2 from suddenly falling when rotating clockwise relative to the armrest component 1;

[0042] One end of the damper 3 is rotatably connected to the armrest assembly 1, and the other end of the damper 3 is rotatably connected to the main body assembly 2;

[0043] The damper 3 is provided with an elastic member 4 for pushing the main body component 2 to rotate counterclockwise relative to the armrest component 1 when the main body component 2 rotates counterclockwise relative to the armrest component 1 .

[0044] The damper 3 is a structure with large resistance and can be retracted. The damper 3 can realize the damping function by friction, or by compressing the space. The damper 3 is a conventional component in the prior art, and its working principle and specific structure refer to the prior art.

[0045] Specifically: the damper 3 is arranged in the middle of the main body component 2 in the width direction.

[0046] refer to Figures 2 to 4 The main body component 2 is provided with a crossbeam 21, and the crossbeam 21 is arranged along the width direction of the main body component 2. The damper 3 is rotatably connected to the main body component 2 through the crossbeam 21. The crossbeam 21 can be fixed to the main body component 2 by screws, and the main body component 2 can include a frame, and the crossbeam 21 can be fixed to the frame by screws.

[0047] Wherein: a first connector 31 is arranged on the crossbeam 21, and the first connector 31 includes a connecting plate 311, and the connecting plates 311 are two, and a cavity is formed between the two connecting plates 311, and a part of the damper 3 is located in the cavity, and the damper 3 is rotatably connected to the cavity through a first rotating shaft 312.

[0048] Solution 1: The first connector 31 is fixed to the crossbeam 21. The first connector 31 can be welded to the crossbeam 21, or the first connector 31 can be fixed to the crossbeam 21 by screws.

[0049] Solution 2: The first connector 31 is rotatably connected to the cross beam 21 via a shaft, a protrusion is provided on the lower side of the cross beam 21, and an axial hole matching the shaft is provided on the protrusion.

[0050] Assuming that the end of the damper 3 connected to the first connector 31 is the front end, when the first connector 31 is fixed to the cross beam 21, the front end of the damper 3 is located between the cross beam 21 and the handrail assembly 1. At this time, the elastic member may exert a certain upward force on the main assembly 2, causing the main assembly 2 to be unstable. By rotating the first connector 31 to connect to the cross beam 21, after the main assembly 2 is unfolded, that is, when the main assembly 2 is in a horizontal state or a substantially horizontal state, the front end of the damper 3 can extend to the end of the cross beam 21 away from the handrail assembly 1, so that the elastic member exerts a force diagonally downward, thereby making the main assembly 2 more stable.

[0051] Specifically: the armrest assembly 1 is provided with a second connector 32 , and the damper 3 is rotatably connected to the armrest assembly 1 via the second connector 32 .

[0052] refer to Figure 3 to Figure 4 The second connector 32 includes a fixing plate 321 and a connecting plate 311 perpendicular to the fixing plate 321. The fixing plate 321 and the connecting plate 311 are an integrated structure. The fixing plate 321 is fixed to the armrest assembly 1. The damper 3 is rotatably connected to the connecting plate 311 via a second rotating shaft 323. The fixing plate 321 can be fixed to the armrest assembly 1 by screws, or welded to the armrest assembly 1.

[0053] The damper 3 includes an inner rod and an outer rod sleeved on the inner rod, the inner rod is rotatably connected to the handrail assembly 1, and the outer rod is rotatably connected to the main assembly 2. A rubber layer can be provided between the inner rod and the outer rod to increase friction.

[0054] Specifically, the elastic member 4 is a spring sleeved on the damper 3. The elastic member 4 may also be replaced by other structures with specific elastic deformation functions.

[0055] The elastic member 4 can be sleeved on the inner rod, with one end of the elastic member 4 abutting against the outer rod and the other end abutting against the second connector.

[0056] The elastic member can also be sleeved on the entire damper, with one end abutting against the first connector and the other end abutting against the second connector.

[0057] The elastic member may also be arranged inside the outer rod, with one end abutting against the inner rod and the other end abutting against an end of the inner rod away from the outer rod.

[0058] The working principle of this embodiment:

[0059] When the main assembly 2 is unfolded, the main assembly 2 rotates clockwise from a vertical state to a horizontal state. During the rotation of the main assembly 2, the damper 3 provides a certain supporting force to prevent the main assembly 2 from falling suddenly. During the clockwise rotation of the main assembly 2, the elastic member stores energy.

[0060] When the main body component 2 is folded, the main body component 2 rotates counterclockwise from a horizontal state to a vertical state. During the rotation of the main body component 2, the energy release of the elastic member can provide a certain thrust, making the operation of the main body component 2 during the counterclockwise rotation process more labor-saving.

[0061] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
